CW1128/1179/1198 telephone cables are ideal when screening is required on telephone systems. The aluminium tape provides high levels of EMI protection (and also works as a moisture barrier on non jelly filled cables). The steel wire armour provides superb mechanical protection making the cables suitable for direct burial and exposed installations. The outer sheath is made from tough, durable polyethylene or external grade PVC which is UV and sunlight resistant. The cores are bedded in petroleum jelly to prevent the ingress of moisture.
